My wife have been using micromax x395 for about 6 months now and have not encountered any problem during her usage. I bought it for Rs 5000 and it has 240x320 screen,audio is loud in fact very loud but good quality, this is single sim gsm mobile, build quality is average but not bad, good internet connectivity options, i use airtel you have to enter the internet settings for all micromax mobiles manually, Only downside is panel gets scratches easily and is very expensive to replace about Rs 800 plus for my model and we cannot use any other ear phones other than supplied by company which is expensive too..
